Rotation of the rotatable member relative to the fixed member causes contact between the first inclined surface and the second inclined surface to press the battery cable terminal to the buttery terminal.     A terminal connector clamp for top post batteries includes opposing, first and second terminal connector flanges and aligned apertures in the flanges adapted for the reception of a connecting shaft.   A connecting shaft having a long axis is adapted for placement through the apertures and has at one end a stop member adapted to engage an outside surface of the first connector flange.          The rotatable member is operatively connected to an opposite end of the connecting shaft and is rotatable substantially about the long axis of the connecting shaft.        A fixed member is operatively engaged to an outside surface of the second connector flange and has a second inclined surface, the second inclined surface being substantially juxtaposed to the first inclined surface.    Rotation of the rotatable member causes sliding contact between the respective inclined surfaces, and axial movement of the fixed member and the second connector flange away from the rotatable member and toward the first connector flange to close the connector flanges against the terminal post.    The invention can be provided as an add-on device for existing terminal connector clamps, as an integral terminal  connector clamp construction, or a buttery cable construction.    A second embodiment is disclosed for batteries with side post terminals.

Patent CA-2027816-A1 (CA)
Inventor: SHARPE RANDALL B
IPC: H04J3/06
Filed: 1990-10-17
Abstract: A fiber optic telecommunication system has master site linked to a plurality of subscriber interface sites by a single pair of optical fibers. Downlink messages are transmitted in a continuous TDM format over a first optical fiber from the master site to subscriber interface sites, and in a burst mode TDMA format over a second optical fiber from the subscriber interface sites to the master site.  Each subscriber interface site is coupled to the optical fiber link by way of a multiple fan-out fiber coupling pedestal  at a common location on the fiber pair.  To prevent collisions between successive uplink bursts from the subscriber interface sites, a guard band separates successive uplink messages from one another. The guard band duration accommodates optical fiber transmission distance between the common location on the uplink optical  fiber and the subscriber  interface site whose differential optical fiber transmission distance from the common location is greatest.   A subscriber location has a television decoder associated with the subscriber's television set, through which  television  channel  selection  signals  are  input by the subscriber for transmission from the subscriber interface site to the master site. Power is provided by way of a replaceable battery pack,  housed  in  a  subterrestrial  bell  jar  configuration, effectively insulating the battery pack from extreme temperature changes and the intrusion of moisture.

Patent CA-2035925-A1 (CA)
Inventor: SCHRODER JORIS
IPC: B66B1/18
Filed: 1991-02-07
Abstract: In this method, target calls (R~~) are definitively allocated immediately to the individual lifts (N) for serving of the call by reason of higher rank and lower rank function requirements and these allocations are indicated immediately on the input storeys (E1 to E16). For this purpose, a weighted sum corresponding to higher rank function requirements is formed from partial operating costs (K1 to K n), this sum is modified into operating costs (K NR) in the sense of lower rank function requirements by means of variable bonus and penalty point factors (BF1...; MF1...) and a target call (R~~) is allocated to the lift (N) with the lowest operating costs (K NR). A target call allocation algorithm (ZZA) according to steps 1 to 6 (SR1 to SR6) with subordinate algorithms for the bonus and penalty point tracking (NFA) and the costs computation (KBA) serves for implementation of this method. The bonus and penalty point factors (BF1...; MF1...) are continuously made to follow the traffic volume or the cage load group by group or lift by lift with the tracking algorithm (NFA).      The computation of the operating costs (K NR) takes place in the costs computation algorithm (KBA) according to a special costs formula, wherein the re-adjusted bonus and penalty point factors (BF1...; MF1...) act multiplicatively on a six-part partial costs sum. This allocation procedure improves above all the user friendliness and the quantitative aspects "waiting times" and "times to target". It utilises capacity reserves at low traffic for additional function requirements on the serving of calls.

Title: Ultrasonic rotary horn
Inventor: NEUWIRTH JOSEPH G
IPC: B06B3/02
Filed: 1991-04-23
Abstract: An ultrasonic rotary horn intended to be excited at a frequency of from about 18 to about 60 kHz, which horn is shaped, solid metal object having a radial surface terminated by a first end and a second end, and a rotational axis, in which each of the ends is defined by a surface. The diameter of the horn can vary from about 4 cm to about 19 cm. The width of the horn at the radial surface is in the range of from about 0.6 cm to about 13 cm. The thickness of the horn at its rotational axis is from about 0.6 cm to about 15 cm and is independent of the width of the horn at the radial surface. The horn has a mass in the range of from about 0.06 kg to about 30 kg. The diameter, width, and thickness values are selected for a desired frequency so that the horn, upon being excited by ultrasonic energy at such frequency which is input at the rotational axis at, and substantially perpendicular to, one or both ends, is adapted to resonate in a manner such that: (1) the excited end moves substantially in phase with the movement of the source of excitation; (2) the opposing end, whether or not it is actively excited, moves substantially out of phase with the movement of the excited end; (3) said radial work-contacting surface also moves substantially out of phase with the movement of the excited end; and (4) said horn exhibits a single nodal point at its geometric center.      In various preferred embodiments, the horn independently includes hubs on each of the two ends; the hubs are integral parts of the horns the horn includes threaded studs which protrude from the ends or from the hubs, if present; and/or the studs are integral parts of the horn. In addition, the radial surface can have a linear or nonlinear profile. The ultrasonic rotary horn of the present invention is particularly useful in continuous processes for bonding together two or more layers of at least partly thermoplastic materials, such as woven and nonwoven fabrics and films.

Title: Ultrasonic carcass inspection
Inventor: RAYMOND DONALD P
IPC: G01N33/12
Filed: 1991-08-07
Abstract: Abstract A meat carcass is inspected ultrasonically to determine its fat-to-lean ratio and to obtain a three-dimensional computer image of the interior of the carcass showing the location, shape and nature of the various pixels of different materials (fat, lean, and possibly also bone, abscesses or other tissues) in the carcass.  These results are achieved by passing ultrasonic pulses into and through the carcass, measuring the timing of both transmitted pulses and return pulses that are reflected from the carcass surfaces and from successive planes between the internal pixels, and  measuring the relative intensities of the reflected pulses,  the latter measurement providing data on the attenuation coefficients of the various pixels from which their nature can be determined. The velocities of the ultrasonic pulses in the different materials being known, as well as their attenuation coefficients, a computer can calculate the fat-to-lean ratio and can construct the desired three-dimensional image.
